ABB FCC/S1.2.2.1 Fan Coil Controller, 2 x 0-10 V, MDRC

Description

Introduction

The ABB FCC/S1.2.2.1 (Product ID: 2CDG110213R0011) is an MDRC KNX (TP) device designed for the comprehensive control of fan coil units in building automation environments. Operating with an IP20 degree of protection, this unit features an integrated room temperature controller that directly controls its onboard outputs, optimizing heating and cooling performance without requiring external RTC hardware. This device is part of our KNX system components range.

Engineered with 5 total outputs and 4 digital inputs, the FCC/S1.2.2.1 provides flexible actuation for two analog valves or a single 6-way valve drive via two 0-10 V analog outputs. It also includes 3 relay outputs for 3-stage fan speed control and supports additional auxiliary heating loads up to 16 A on a relay output, alongside manual operation capabilities and diagnostic integration via the ABB i-bus Tool.

Key Features

• 5 total outputs including 2 analog 0-10 V outputs and 3 fan relay outputs.
• 4 digital inputs for room status monitoring and external sensor connections.
• Relay switching capacity up to 16 A for auxiliary heating loads.
• Integrated room temperature controller and special Valve Protection functionality.
• Modular DIN-Rail Component (MDRC) form factor with IP20 protection.
• Manual operation interface for direct manual control.
• Native KNX (TP) bus system compatibility.
• Advanced diagnostic support via ABB i-bus Tool.

Benefits

• Integrated Room Temperature Control: Built-in controller directly regulates device outputs for efficient room temperature management.
• Flexible Valve Actuation: Supports two analog valves or one 6-way valve drive for heating and cooling via two 0-10 V analog outputs.
• Multi-Stage Fan Management: Provides 3 dedicated relay outputs for controlling 3-stage fan coil speed setups.
• High auxiliary load capacity: Includes a relay output capable of switching additional loads up to 16 A, such as auxiliary heating elements.
• Versatile Input Options: Features 4 digital inputs to monitor window contacts, dew point sensors, level sensors, temperature sensors, or connect analog room control units (SAR/A or SAF/A).
• Streamlined Diagnostics & Maintenance: Features manual operation controls and supports the ABB i-bus Tool for simplified commissioning and troubleshooting.
